Definitions

• Shisha devices are typically used to smoke tobacco and are configured such that vapor and smoke pass through a water basin before inhalation by a consumer. Shisha devices may include one outlet or more than one outlet so that the device can be used by more than one consumer at a time. Use of shisha devices is considered by many to be a leisure activity and a social experience.
• the vessel comprises a headspace in communication with the outlet for delivering the aerosol to the user.
• the aerosol generating element is in fluid connection with the vessel and is configured to heat the aerosol generating substrate.
• the aerosol condensation particle dispenser is configured to deliver at least one aerosol condensation particle to the airflow path.
• the methods, devices, and systems described herein may provide for increased visible aerosol, increased delivery of total aerosol mass, or increased visible aerosol and increased delivery of total aerosol mass in shisha devices comprising aerosol generating elements having electric heaters that heat but do not combust an aerosol generating substrate.
• the increase in one or both of visible aerosol and total aerosol mass results from introducing the aerosol condensation particle into an airflow path configured to carry aerosol generated by heating the aerosol generating substrate to an outlet for delivery to a user by inhalation.
• the aerosol condensation particle promotes a process of heterogeneous nucleation, which increases one or both of visible aerosol and total aerosol mass.
• aerosol condensation particle refers to any particulate matter that may act as a seed or a nucleation site on or about which vapor particles may condense to form solid particles or liquid droplets in the form of an aerosol.
• the aerosol condensation particle may be a solid particle or may be a liquid droplet.
• the methods, devices and systems described herein may introduce one aerosol condensation particle to the airflow path. However, typically the methods, devices and systems described herein introduce a plurality of aerosol condensation particles into the airflow path. It may be advantageous to provide the at least one aerosol condensation particle in the airflow path at the location at which the vapor concentration is at its greatest.
• a susceptor may comprise any suitable proportion of ferromagnetic or paramagnetic materials.
• a susceptor may comprises at least 5%, at least 20%, at least 50% or at least 90% of ferromagnetic or paramagnetic materials.
• the susceptor may be heated to a temperature in excess of 250 degrees Celsius.
• Suitable susceptors may comprise a non-metallic core with a metal layer disposed on the non-metallic core, for example metallic tracks formed on a surface of a ceramic core.
• the cartridge may comprise a thermally conductive housing.
• the housing may be formed from aluminium, copper, zinc, nickel, silver, and combinations thereof.
• the housing may be formed from aluminium.
• the cartridge is formed from one or more material less thermally conductive than aluminium.
• the housing may be formed from any suitable thermally stable polymeric material. If the material is sufficiently thin sufficient heat may be transferred through the housing despite the housing being formed from material that is not particularly thermally conductive.
• the cartridge may comprise one or more apertures formed in the top and bottom of the housing to allow air flow through the cartridge when in use.
• the top of the receptacle comprises one or more apertures
• at least some of the apertures in the top of the cartridge may be aligned with the apertures in the top of the receptacle.
• at least some of the apertures in the top of the cartridge may be offset or not aligned with the apertures in the top of the receptacle.
• the cartridge may comprise an alignment feature configured to mate with a complementary alignment feature of the receptacle to locate the apertures of the cartridge relative to the apertures of the receptacle.
• the cartridge may comprise an alignment feature configured to align the apertures of the cartridge with the apertures of the receptacle when the cartridge is inserted into the receptacle.
• the apertures in the housing of the cartridge may be covered during storage to prevent aerosol generating substrate stored in the cartridge from spilling out of the cartridge.
• the apertures in the housing may have dimensions sufficiently small to prevent or inhibit the aerosol generating substrate from exiting the cartridge. If the apertures are covered, a consumer may remove the cover prior to inserting the cartridge into the receptacle.
• the receptacle is configured to puncture the cartridge to form apertures in the cartridge.
• the receptacle may be configured to puncture the top of the cartridge.
• a shisha device of the invention may have any suitable air management.
• puffing action from the user will create a suction effect causing a low pressure inside the device which will cause external air to flow through air inlet of the device, into the fresh air inlet channel, and into the receptacle of the aerosol generating element.
• the air may then flow through aerosol generating substrate or a cartridge containing the substrate in the receptacle to carry aerosol through the aerosol outlet of the receptacle.
• One or more of natural fruit juices, botanicals, and herbal infusions may be added to the water for flavouring.
• the amount of liquid added should cover a portion of the conduit but should not exceed a fill level mark that may optionally exist on the vessel.
• the vessel may then be reassembled to the shisha device.
• a portion of the aerosol generating element may be removed or opened to allow the aerosol generating substrate or the cartridge to be inserted into the receptacle.
• the aerosol generating element may then be reassembled or closed.
• the device may then be turned on by a user operating the activation element. This may turn on the electric heater of the aerosol generating element to heat the aerosol generating substrate in the receptacle.

• the aerosol generating element 130 also includes a heating element 160 that forms at least one surface of the receptacle 140. In the depicted embodiment, the heating element 160 defines the top and side surfaces of the receptacle 140.
• the aerosol generating element 130 also includes a fresh air inlet channel 170 that draws fresh air into the device 100. A portion of the fresh air inlet channel 170 is formed by the heating element 160 to heat the air before the air enters the receptacle 140.
